1990 300SL, 2004 E320
I purchased a late automatic self-dimming interior rear view mirror from a late SL. I want to install it into my '90 SL. Has anyone installed and wired this later mirror in an earlier R129?? What are the removal procedures of the old one? And the steps or warnings of what's to follow toward the success of the retrofit? Or is it a futile attempt at RR of the old one??
